TABLE Application filed May 19, 1930. Serial No. 458,565.

The invention relates to tables, and particularly to tables of theextension leaf type, and has for its object to provide a table of thischaracter in which the extension leaves are positioned beneath the tabletop in parallel relation thereto when in. retracted inoperativeposition.

. A further object is to provide a table of this character provided witha table top having depending side flanges within which the extensionleaves are adapted to be nested when in retracted position, said topbeing tiltable relative to the table frame to permit withdrawal of theleaves to operative extended position. 1 c

A further object is to provide. a table of this character havingextension leaves adapted to be locked in retracted position and meansfor automatically projecting said leaves to operative extended positionupon release of the means locking said leaves in retracted position.

A further object is to provide a table of this character having its topflexibly connected to the table frame and controlled by guide meanspermitting only tilting of the top relative to the frame and preventingsimultaneous equal upward movement of all points ofithe top relative tothe frame.

A. further object is to provide a table of this character having meanscarried the top for locking the extension leaves in retracted. position,means for automatically projecting the leaves to operative extended 35position upon predetermined shifting of the table top to release thelocking means, and

means for guiding the shifting of the top in the predetermined manner. i

With the above and other objects in view,

40 the invention resides in the combination and arrangement of parts ashereinafter set forth,

shown in the drawings,described and claimed,

it being understood that changes in the pre cise embodiment of theinvention may be 45 made within the scope of what is claimed withoutdeparting from the spirit of the invention. 1

Referring to the drawings, which illustrate the preferred embodiment ofthe invention, the numeral 10 designates a table frame comprising endrails 11, side rails12 and legs 13. The upper portion of the end ofeachside rail 12 is cut away at 14, and mounted centrally 7 in said cut-awayportions 14 and extending transversely of the table framebetween theopposite side rails are guide members 15. Guide members 15 arepreferably T-shaped the stem of the T being supported by said side railsand 30 he upper surfaces of the guide members being substantially levelwith the top of the side and end rails of the table frame. Mounted onthe table frame is a table top 16, preferably of conventional sheetmetal construction, and having flanges 17 depending from' its perimeterin the conventional manner; said flanges receiving a supporting frame18therein which includes a central longitudinal cleat 19. At each end ofthe table top a headed pin 20 depends vertically from the cleat 19 andpasses through an aperture 21 formed in the guide member 15therebeneath, Figure 9, said aperture being of a size to'permit the pinto have a slight lateral movement as well as free longitudinal movementtherein. Springs 22 are carried by cleat 19 and are connected to the endrails 11 adjacent the lower edges thereof. The springs 22 and pins 20form the sole connection between the table top and table frame;

V the pins serving to correctly position the table 7 extending throughthe cut-away portions 14:

of the side rails of the frame. Supporting frames 24, carried by theunder sides of guide members 15 and projecting laterally therefrom,support the bars 23 in operativehorizontal position. Mounted on theouter ends of bars 23 at the opposite sides of the table frame areextension leaves 25, said leaves being of a length less than the innerdimensions of the supporting frame 18 and of a width less than thedistance between the cleat 19 and the supporting frame-whereby theextension leaves may be nested within the depending flanges of the tabletop and so held in retracted position. Springs 26 extend between theinnerends of the bars 23' and the opposite side of the table frame, saidsprings acting to force said bars and extension leaves outwardly of thetable top into extended position. Stops 27 are carried by the bars 23tolimit the outward movement of the bars and extension leaves relative tothe table top whereby said leaves will not be projected outwardly beyondoperative extended position by springs 26. Atthe center of the innerside of each end rail and near the lower edge thereof is mounted aV-shaped guide block 28, having its lower point out oif, and above block28 a pin 29 is secured to cleat 19 in vertically depending relation,said pin 29 having at its lower end a perpendicularly bent hook portion30 disposable beneath said block.

'When the table is'inits normal position with the extension leaves 25 inretracted posi- 7 with the leaves. .Up-ward tilting movement tion, thetable top telescopes and rests upon said leaves, and thedependingflanges 17 of the top, into which said leaves nest, lock theleaves in retracted position against the action of the springs 26; thesprings 22 drawing the of one side of'the tabletop against the action ofsprings 22 releases'one of the extension leaves from its telescopedinterlocked relation with the top; and said leaf is then automaticallyprojected outwardly of the frame- 7 by its cooperating springs 26. Theoutward movement of said leaf is limited .by the stops 27which stop saidleaf at its extended position at a point clear of and adjacent the outeredge of the table top, so that upon release of the top to its normalhorizontal position the top and extension leaf are in substantiallycontacting relation at their proximate edges and form a continuous'tabletop. Tilting connection between the frame. 1

The top is effectively prevented from excessive tilting relative to theframe by the headedepins 20 whose head engages the guides 15 to limitsaid tilting movement; the apertures '21 in guides 15 through which saidpins pass being of a size to permit the slight tilting of the pintherein. The combination of the V- shaped guide blocks 28 and the pins29 serves to guide the tilting movement of the top and to preventsimultaneous equal upward movement of all parts of the top relative othe frame. Upon tilting of the top the hook portion 30 of pin 29 isswung clear of the bottomofthe block 28 and engages the upwardlyoutwardly inclined sides of said block whose inclination permitscontinued tilting ofthe top as is required to'release the extension leaffrom its nested position beneath the top. Upon direct upward applicationof force to the table top in a manner tending to simultaneously equallymove all parts of the top relative to the table frame, the hook portion30 of pin 29 engages the under side of the block and prevents movementof the top relative to the frame. Thus it is made possible tocentrallygrasp the table top to carry the table without causing tiltingor other movement of the top relative to the frame, and it is notnecessary for the frame itself to be grasped as would otherwise benecessa-ry in a table of this construction'having no fixed table top andtable The invention having been set forth, what is claimed as new anduseful is:
